Tepco’s ice wall runs into glitch at Fukushima No. 1 AFP-JIJI, REUTERS JUN 18, 2014 Tokyo Electric Power Co. says the refrigerated ice wall being built to slow the movement of water beneath damaged reactors at the Fukushima No. 1 nuclear plant isn’t working as expected. Tepco said the project, which remains in its early stages, is experiencing a problem with an inner ice wall designed to contain highly radioactive water that is draining from the basements of the wrecked reactors. “We have yet to form an ice plug because we can’t get the temperature low enough to freeze the water,” a Tepco spokesman said Tuesday. Trenches are being dug for a huge network of pipes under the plant that will have refrigerant pumped through them. If successful, it would freeze the soil and form a physical barrier, significantly slowing the rate at which uncontaminated groundwater flows into the reactor basements and becomes contaminated. http://www.japantimes.co.jp/news/2014/06/18/national/effort-to-freeze-radioactive-fukushima-water-hits-snag/#.U7-BplaGJBV
